As documented in bug 1085230 comment 12, we should use 439877632 (419.5*1024*1024).

The size of 419.5 comes from the output of gdisk on the gpt_bothO_big.bin.

Comment on attachment 8635324 [details] Flame KK PR Slightly concerned about people getting confused from this..

We placed in the partitioning in the partition sector, we had not updated the system partition size; hence we still had the issue in bug 1181372 Made a build and flashed it. Build is located here: https://drive.google.com/a/mozilla.com/file/d/0B_0LdM1CVycIdWRLdUJkQ2lXb3c/view?usp=sharing You will need the latest contributor build flashed first : http://bit.ly/1NWi45L Output of adb shell df /system Filesystem Size Used Free Blksize /system 412.5M 209.5M 203.0M 4096

Chris, I think we should make it clear on MDN that users without the proper partitionning will not be able to flash system.img now :). The error they will get is: > Flashing out/target/product/flame/system.img failed because the image was too large. They should update base image in this case.

Ok, so I've added a note to cover this at the bottom of the following section of the Flame guide: https://developer.mozilla.org/en-US/Firefox_OS/Phone_guide/Flame/Updating_your_Flame#Updating_your_Flame_to_a_nightly_build Is this ok?

That looks good to me :) Thanks !

I encountered a weird case. Bug 1214298. FYI.
